Abstract

The idea of using the information present in the combination of sensorsignals for the identification of substances rather than to rely on the selectivity of single sensor elements /1, 2, 3, 4/ has lead to the application of the methods of pattern recognition (PARC) to chemo sensor signals. These methods are described e.g. in /5/. While the methods of PARC levels 1 and 2 serve the purpose of identification only, the methods of level 3 and 4 yield the identification and concentration at the same time. The latter two methods however are applicable only if the superposition law holds for the sensorsignals, which is rarely the case with chemosensors. Frequently however it is possible to find an artifical superposition plane by transformation of the sensor — signals /6/.
